View a sample reportFlint housing stock
Flint has roughly 42,531 housing units and about 80% of them are single-family detached. Homes built in a single stretch tend to wear out in the same places at the same time. That is why when somewhere was built is the first thing worth knowing about it.
The busiest stretch of building here was the 1950s: 13,483 homes, about 32% of everything standing today.
The median owner-occupied home here is valued at $43,300. Only 54% of occupied homes are owner-occupied, so a good share of what we inspect here is bought as a rental or sold with tenants in place — which changes what access on the day looks like. There are around 741 manufactured and mobile homes in Flint. Those are a different inspection — the questions are about the frame, the anchoring and the skirting rather than a basement. Around 2,217 homes sit in two-to-four unit buildings, where a shared roof, a shared wall and sometimes a shared furnace mean the report has to be clear about where one unit stops.
None of this says anything about the specific house you are buying. It is the shortlist a Flint home inspector works through in a home of this age, and every item on it gets photographed and written up whichever way it turns out.
Housing figures: US Census Bureau, American Community Survey 2022 five-year estimates.
When Flint was built
86% of homes here run on utility gas, and 13 still heat with oil. If yours is one of them, the tank is the thing to ask about — where it is, and whether it was ever buried. Another 376 use bottled or LP gas.
Local knowledge
Flint is an older housing market than almost anywhere else we work. Of about 42,531 units, roughly 13,483 were built in the 1950s and 10,108 before 1940 — and taken together, about 93% of the city’s housing predates 1980. Around 80% is single-family detached.
That shapes what an inspection is for. On stock this age, almost nothing you are looking at is original: the roof, the furnace, the water heater, the service panel and much of the plumbing have each been replaced or altered at least once, by different people, to different standards, across seventy or ninety years. The question is never what the house was built with. It is what is in it now and how much life is left in it.
The other thing that comes up in every Flint conversation is water, and it deserves accurate treatment rather than either silence or drama. The City finished replacing its known lead service lines in 2026. What that program did and did not cover matters to a buyer, and it has its own section below.
Before you buy
The water question, answered with the City’s own numbers
We are not going to write around this, and we are not going to sensationalize it. Here is what the City of Flint published on 13 August 2026, in its own figures.
The last known active lead service line was removed on 31 July 2026. Roughly 11,600 lines were replaced out of almost 32,000 properties excavated and checked, in an effort the City puts at around $140 million — including about 500 additional lead lines found while completing the settlement agreement that had already covered over 11,000. The City also states that Flint has reached a decade of compliance with state and federal standards for lead in drinking water, and that the January to June 2026 monitoring period produced a 90th percentile calculation of 3 parts per billion — against Michigan’s tighter 12 ppb standard that took effect in 2025 and a federal standard of 15 ppb.
Those are the City’s words and the City’s numbers, including the word known, which we have kept everywhere the City uses it. We are not in a position to pronounce on anyone’s drinking water and we are not going to pretend otherwise.
What is squarely a property question is the part the program never covered. A service line is the pipe running from the main to the building, and replacing it was the City’s work. The plumbing inside the house belongs to the owner. The City’s own sampling categories make the distinction visible: alongside homes served by a lead service line, it samples what it calls Tier 3 sites — single-family residences with interior copper plumbing with lead solder installed before 1988. In a city where about 93% of the housing predates 1980, that is a question about the building rather than the street.
To be plain about our own limits: a home inspection does not test water. We do not take water samples and we do not analyze them. What a buyer’s inspection does is report the accessible plumbing as found — what materials are visible, their condition, evidence of leaks or past repairs, water heater age and condition, functional flow and drainage — and say clearly what was concealed. Water quality testing is a laboratory question, and the City and the State run programs for it.
Permits and rentals
The practical details are easy to miss and they affect timelines.
The City’s Building & Safety Division provides inspection services for all trades — building, electrical, plumbing and mechanical — with inspectors licensed by the State of Michigan. The public office runs Monday to Thursday, 9am to 3pm, which is a shorter week than most departments in this region and worth planning around if you intend to start work soon after closing.
The forms tell you what else the City runs. There is a rental registration and a rental housing inspection checklist, a rental inspection consent form, and — unusually — a non-rental affidavit, the document you sign to establish that a property is not being rented. Permit applications are published in English and Spanish. We did not find a published inspection cycle or certificate validity period, so we are not going to state one; the Building & Safety office is the place to confirm it.
There is also a Residential Abandoned Property Registration Program, administered through a third-party registry, under which mortgagees or their servicers must register a qualifying property and pay a one-time $250 fee. If you are buying something that has been sitting, that is worth establishing before closing rather than after — and a house that has stood empty and unheated is a different inspection from one that has been lived in.
Drainage and the sewer system
The City reports approximately 600 miles of sanitary sewers, 350 miles of storm sewers and 600 miles of water mains, maintained by a water service center whose phones are answered around the clock.
The Sewer Department also runs smoke testing neighborhood by neighborhood — a test that pushes non-toxic smoke through the sewer to reveal defects, cross-connections and improper connections by where it comes out. One was carried out in the Evergreen Valley area on 30 May 2026. If you see a notice for the street you are buying on, it is routine work rather than a warning sign.
What an inspection covers is how the property itself handles water: accessible grading and whether the ground sheds water away from the foundation, gutters and downspouts and where they discharge, foundation conditions, the basement or crawlspace, floor drains and any sump equipment, and the accessible drain plumbing inside — all documented as found, with what could not be seen said plainly.
The buried line
The water service line has had a great deal of attention in Flint. The sanitary lateral running from the house to the sewer main has had almost none, and it is a different pipe doing a different job.
On a house from the 1950s it has been in the ground about seventy years, and on a prewar house longer than that — ample time for roots to find a joint, for ground movement to displace a section, or for a repair to have been made that nobody now remembers. We will not name a material from a build year, because no authoritative source establishes what Flint laterals are generally made of.
A sewer camera inspection records what is actually inside — roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not — and it is added to the same visit rather than booked separately.
Alongside it, commercial building inspections follow the CCPIA standard for offices, retail, multifamily and warehouse property, and radon testing or mold inspection and testing can be added to a residential or commercial visit.

Desmond SheppardFlint, MINoah Scott was very thorough and explaining things to us, especially in regard to a possible mold problem.
Claudette GranvilleFlint, MII recently hired Trademark for a full home inspection on a new purchase, including sewer scope and radon testing. It was a phenomenal experience from beginning to end. Our inspector, Mitch, did a fantastic job explaining all the findings, and the digital report with photos and videos was superb. Would definitely recommend without hesitation.

Questions
The City states that the last known active lead service line was removed on 31 July 2026, completing the replacement of all known lead service lines. In its figures, roughly 11,600 lines were replaced out of almost 32,000 properties excavated and checked, in an effort put at around $140 million. Those are the City’s words and numbers, and we have kept the word known where the City uses it. The City also states it has reached a decade of compliance with state and federal standards for lead in drinking water.
No. We do not take water samples and we do not analyze them, and we would rather say that plainly than let anyone assume otherwise. What an inspection covers is the accessible plumbing as found — visible materials, condition, evidence of leaks or past repairs, water heater age and condition, functional flow and drainage — and what was concealed. Water quality testing is a laboratory matter, and the City and the State run programs for it.
No, and this is the distinction worth understanding. A service line is the pipe running from the main to the building, and replacing it was the City’s work. The plumbing inside the house belongs to the property owner and was never part of that program. The City’s own sampling categories reflect it — alongside homes served by a lead service line, it samples what it calls Tier 3 sites: single-family residences with interior copper plumbing with lead solder installed before 1988. On a city where about 93% of housing predates 1980, that is a question about the building.
Old, and concentrated. Of about 42,531 housing units, roughly 13,483 were built in the 1950s and 10,108 before 1940, with 7,117 from the 1960s and 4,978 from the 1940s. Fewer than 3,000 units have been built since 1980, so about 93% of the stock predates it. Around 80% is single-family detached. On housing that age the roof covering, furnace, water heater, electrical service and much of the plumbing have all been replaced or altered at least once.
The Building & Safety office runs Monday to Thursday, 9am to 3pm — a shorter public week than most departments in the region. The division provides inspection services for all trades, building, electrical, plumbing and mechanical, and states that its inspectors are licensed by the State of Michigan. If your plan for a property depends on permits or inspections soon after closing, build the timeline around those hours.
Yes. The City runs a Residential Abandoned Property Registration Program through a third-party registry, under which mortgagees or their servicers must register a qualifying property and pay a one-time $250 fee. Establish where that stands with your title company before closing. Separately, a house that has been standing empty and possibly unheated is a different inspection from an occupied one — plumbing, heating, the roof and any evidence of water entry all behave differently in a building nobody has been using.
No, it is routine. Smoke testing pushes non-toxic smoke through the sanitary sewer so that defects, cross-connections and improper connections show up by where the smoke escapes. The City’s Sewer Department runs it neighborhood by neighborhood — one was carried out in the Evergreen Valley area on 30 May 2026. Seeing a notice means the system is being checked, not that something has gone wrong at your address.
It is worth considering, and it is a different pipe from the one that has had all the attention. The sanitary lateral running from the house to the sewer main has been in the ground about seventy years on a 1950s house and longer on a prewar one, and no visual inspection sees inside it. We will not guess a material from a build year — no authoritative source establishes what Flint laterals are generally made of. Putting a camera down the line documents roots, cracks, displaced joints, bellies or blockages where they exist, and is added to the same appointment.
